IMPROVEMENT IN MACHINES FOR STAKING, GLASSING. AND PERCHING SKINS.

Specification forming part of Letters Patent No. 139,442, dated May 27,1873; application Iiled March 3, 1873.

To all whom it may concern:

Be it known that I, WILLIAM A. WATsoN, of Beverly, in the county ofEssex and State of Massachusetts, have invented a new and useful Machinefor Staking, Glassing, and Perching Skins, of which the following is aspeciiication This invention relates to a machine c011- structed andarranged to be driven by steam or other power, and which shall performall of the more laborious part of the work, the operator only holdingthe skin and bringing all parts of the surface under Jche action of themachine; and the invention consists in a reciprocating beam, arrangedrelatively'to' one or more stakes,77 provided with steel or glassblades, which act upon the skin as the lsame is being drawn across theblades by the action of the beam, as is hereinafter more fullydescribed.

Figure l is a front elevation: Fig. 2 is an end elevation taken at theright of Fig. l; and Fig. 3 is a horizontal section taken on line A B,Fig. 1. l

In the drawings, a. is a rigid upright frame secured in bed b; c c arebeveled ways, secured to frame c; and d d is a sliding frame, held inposition by lips e fitting to ways c, as shown in Fig. 3. f f are twowristpins inserted in frame d; and g g are connectingrods extending fromand connecting with both pins f, and similar pins h in cranks i, whichlatter are secured upon the respective ends of shaft j. This shaft isrotated by any desired means, and when thus in action the frame d willhave a vertical reciprocating movement equal to twice the stroke ofcranks-c', the frame d being guided in a vertical line by the ways c, asbefore described. k k is a beam extending from frame d on either or bothsides, as may be desired. lm are the stakes, n is the blade or glass,and o is the skin. In practical use the operator stands at the end ofbeam 7c, facing the stakes, when, by grasping the opposite ends of theskin, he endeavors constantly to extend the same, while the descendingmovements of the beam serve to draw the skin across the blades as it iscarried downward bythe beam, which result is repeated at every descentthereof, the skin being extended and changed relatively to the blades bythe operator as the beam rises. When operating upon the flesh77 side ofthe skin steel blades are employed, while for the grain77 side glass isused, and for the process known as perching one end of the skin may beheld rigidly by a bar, and the other by the operator.

What I claim is- The reciprocating beam K, in combination with stakeslm, substantially as and for the purposes specied.
